PRELIMINARY-TREATMENT TANK.

' Specification of Letters Patent.

Application led August 6, 1914. Serial No. 855,444.

T 0 all Iwhom it m ay conc-ern Be it known that I, EDWARD HALE DICKIE, a citizen of the United States, residing at Goldroad, in the county of Mohave and'4 State of Arizona, have invented certain new and useful Improvements in Preliminary- Treatment Tanks. and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in apparatus for the treatment of numerous kinds of ores, and has for its main object, to provide construction whereby the values within the ores may be brought forcibly into contact with value precipitants, whereby the lbest results are obtainable.

A second object is to provide, in combination with a leaching tank having a horizontal filter' in its bottom, a specific type of agitator, whereby clogging of the filter is prevented; while a third object is to improve upon the general construction of apparatus of the class described. I

vith these and minor objects in view, the

invention resides in certain novel featuresil hereinafter claimed and fully described by reference to the accompanying drawings' ,whereinz- Figure 1 is a vertical section through a leaching tank showing a number of air lifts therein. in elevation: Fig. 2 is a top plan view of the parts shown in Fig. 1: Figf 3 is a detailvertical section taken on the line 3 3 of Fig. 1: Fig. 4 is` an enlarged vertifor the air lifts as well as illustrating a modified Aconstruction of leaching tank Fig. 8 is a top plan view of the parts illustrated in Fig. 7 Fig. 9 is a horizontal section taken on the line 9-9 of Fig. 7: Fig. 10 is a vertical section taken at right angles to Fig. 7 and indicated upon the line 10-10 thereof; Fig. 11 is a detail vertical section taken on the line 11-11 of Fig. 7: Fig. 12 is a side elevation' showing a modified construction of air lift: Fig. 13 is a horizontal section taken` on the line 13-13 of Fig. 12: Fig. 14 is an enlarged vertical section taken on the line 121-14 of Fig. 13.

In the accompanying drawings from Figs. 1 to 6 inclusive, I have shown an upright leaching tank 1 herein shown as formed of cement or other suitable material having similar characteristics, the annular wall 2 and the solid bottom 3 of said tank being preferably formed integrally. As clearly illustrated in Fig.`1, the upper side of the bottom 3 inclines downwardly from one sidel Patented Mar. 28, 1916.

of the tank toward the other, a suitable disv charge spigot 5 being employed at the low side of said inclined upper surface, said spigot communicating with the interior of the tank through a radial passage 6 whose inner end is substantially closed by a rather coarse filtering tile 7. A

Terminating in a planel substantially in horizontal alinement with the upper edge of the opening 6, is a coating 8 ofquartz pebbles or gravel, said coating being laid directly upon the inclined surface 4 of the bottom 3 and receiving, upon its upper surface, a coating 9 of sharp sand or quartz above which a third coating 10 of filtering tile is laid, said coating 10 constituting the bottom proper of the tank 1.

Preferably disposed at a point opposite the spigot 5 and communicating directly with the interiorof the tank above the'ltering bottom, is a tapered discharge opening 11 in which a similarly shaped door 12 is normally seated by means of a wedge or wedges 13 which bear against said door and against suitable guides or stops 14 which are herein shown as carried by the opposite side walls of a U-shaped spout 15. In most lcases it becomes expedient to reinforce the door 12 as indicated at 16 and to likewise The orm of tank, so far described, although acting to eifectively strain or lter any liquid solution within the tank, is prone to become clogged and therefore ineffective to a certain degree. It is to overcome this diliiculty that the construction now to be described is provided.'

Spaced a. suitable ldistance above the upper end of the tank: 1 and preferably'l formed of greater diameter than the same,

is an angle iron ring 17 whose horizontal flange 18 projects outwardly, its upright flange 19 being .secured to a number of stubshafts 2U which project inwardly therefrom and have their inner ends rigidly mounted in suitable brackets 21 carried by a trio of arms 22 which incline upwardly and inwardly and are united by a suitable plate 23. The shafts revolubly support flangedl wheels or pulleys '24 which travel upon an annular angle iron track 25 formed on the upper inner edge of the wall 2, thereby mounting the three arms 22, the ring 17 and parts to be discribed, in such a manner as to allow the same to revolve or rotate.

Suspended from the arms 22 by suitable hangers 27, are a number of air lifts 26 which are here shown in the form of upright tubes around the upper portions of which bands 28 are passed, said bands acting as connections between the bifurcated lower ends 29 of the hangers 27 and said tubes and also acting to secure a number of lower airl tube sections 30 in proper position, the lower ends of said sections 30 being turned inwardly and upwardly as seen more particularly at 31 in Figs. 4, 5 and 6, said lower ends carrying spray nozzles 32 which are of a construction to be described, while the upper ends of said sections 30 each carry one member of a ball and socket coupling 33 to the other members of which air tubes 34 are connected at their lower ends, the UPPer ends of said tubes 34 being in valved communication with a trio of air tubes 35 which overlie the arms 22 and communicate with a coupling 36 which rises from the plate 23, said coupling having a universal connection at 37 with a pressure supply pipe 38.

The nozzles 32 may be of anyl desired construction provided they be so constructedas to form outwardly and upwardly inclining discharge openings 39 through which the air, under pressure, is forced. Said nozzles are also preferably provided with suitable valve cages 40 with` in which ball valves 41 are located, said valves acting normally to clse the upper ends of the portions 31, constituting the lower ends of the tube sections 30.

The inclineddischarge openings 39 are provided in order that a slime or pulp being treated may be forced outwardly, by air pressure, into forciblecontact with a' lining of value precipitating material 42 one of which is located in each of the lifts 26. As probably most clearly seen in Figs. 5 and 6. a value precipitating casing 43 is provided around the outside of each of said lifts 26, each of said casings being formed in upper and lower sections 43 and 43 which are located respectively above and below the bands 28. For the purpose of rotating the frame composed of the three arms 22,1 provide upper and lower friction wheels Yand 51, the latter being mounted upon a horizontal shaft 52 which `is revolu- -bly mounted in a bracket 53 secured to the wall 2, said wheel 51 contacting with the under side of the horizontal flange 18 while the wheel .50 contacts with the upper side of said flange and is revolubly mounted in a fork 54 whose arms are mounted for'vertical movement in yslots 55 formed in the upper end portion of the bracket 53 while oppositely projecting guide shoulders 56, located at right angles to the arms 54, are slidably mounted in upright slots 57 which are likewise formed in the bracket 53, a screw 58 bearing normally against a coiled spring 59 and threaded through the upper end of the bracket 53 acting to normally force said wheel 50 into contact with the flange 18. As clearly seen in the drawings, the shaft 52 may be driven by a suitable pulley 60 or otherwise.

Vith the parts as above described, the solution to be treated may be placed in the tank and the pulley 60 set in motion, therefore causing the ring 17 tol rotate, thus moving the pneumatic lifts 26 through the liquid within the tank during which operation, compressed air is allowed to flow through the pipe 38 to be discharged from the nozzles 32, this discharge of air acting to force the solution within the lifts 26 upwardly therethrough and creating a suction directly above the filtering bottom to the tank thereby not only agitating said solution at all times and causing the same p to contact with the linings' 42, but effectively preventing the accumulation of any,

sediment whatever upon the tile coatingV 10, whereby the filter may operate effectively at all times.

From Figs. 7 to 11 inclusive, I have shown an upright sheet metal tank 61 which corresponds with the tankl previously described, said tank, in this case,4

being provided with a bottom 62 which is preferably though not necessarily formed of red wood, a number-of parallel slats 63 which are notched on theirAlower 'sides as indicated at 64, being disposed upon theI upper side of the bottom 62 and acting ,toy

support a perforated false bottom 65 above which a sheet 66 of cocoa fiber and a second; sheet 67 of duck are secured preferably by` an annular fiber ring 68 through which suitable fastening elements 69 are driven, said elements also passing through the sheet 66 and 67 and into the perforated bottom 65 (see more'particularly Fig. 11).

The entlre structure thus. far described is herein shown as being supported upon a suitable frame 70'upon a horizontal shelf 7], of* which an outturned flange 72 of a central upright tujbe 73 is secured, said tube being also provided with a second laterally extending iange 7-l which is secured to the bottom 62 as indicated in Fig. 7 or by other suitable means. i

As most clearly seen in Fig. 7, the upper end of the tube 73 terminates in the plane in which the upper end of the tank 61 lies, said upper end of the tube 7 3 carrying one member 74 of a ball bearing, the opposite member 75 of which is carried by an upright shaft 76 which rises through the tube 73, said shaft being preferably driven by a worm 77 keyed upon a driveshaft 78 and meshing with a worm gear 79 which is keyed upon said shaft 76.

The bearing member 75 rigidly supports a frame 8'0 which is here shown as including a pair of parallel side bars 81 which are connected respectively at their outer ends and near their centers by transverse bars or blocks 82 and 83. The frame 80 is further provided with a pair-'of `posts 84 which rise from its center and support a transverse bar 85 from which suitable trussl wires 86 incline downwardly and outwardly, said wires being attached to the outer ends of said arms ,81. r

The bar 85 acts not only as a bracingmeans for the arms 81 but supports'a coupling 87 to which an air pressure pipe 88 is universally connected as indicated at 89, said pipe 88 supplying af pair of pressure supply pipes 90 one of which extends outwardly above the right hand end of one of the bars 81 while the opposite tube 90 extends outwardly above the left hand end of the opposite bar (see more particularly Fig. 8). To the tubes 90, upright tubes 91, corresponding to the tubes 34 above described, are connected by flexible tubes 92 as clearly shown in Fig. 7, the intermediate portions of said tubes 91 being secured in position by bands 28 which surround a number of air lifts 26 which are constructed in the same manner as the lifts 26 before described, said bands 28 being provided for the attachment of flexible hangers 27 whose upper ends are preferably secured by means of hooks 93 to the side bars 81.

The operation of the form of invention just described, is as follows: The shaft 78 is rotated by any suitable power, the movement of said shaft acting to rotate the shaft 76 which in turn rotates the bearing member 75 to rotate the arms 81 during which move-` ment they are guided by rollers 24 which are mounted on their outer ends and which run upon the upper edge of the tank 61, the rotation of the bars 81, constituting the frame 80, will of course cause the pneumatic lifts 26 to travel through the solution within the tank thus producing el'ects set forth in connection with the form of the invention first described. If desired, a number of pipes 94 may be provided, said pipes leading into said tank 61 at different elevations and being provided with -cut off valves 95. The tank 61 is also preferably provided with a gate or door 12 which is held normally closed by a wedge 13.

In Figs. 12 to 1l inclusive, a tubular pneumatic lift 96 is illustrated which is preferably constructed of vitriied clay, said tube having a substantially cylindrical extension 97 formed integrally with one of its sides, said extension rising above said tube as indicated at 97 and receiving throughout its length, a metal air supply .tube 98 which communicates with a cylindrical recess 99 in the lower end of said extension 97, said recess receiving one end of a U-shaped pipe 100 which is likewise formed of vitrilied material and whose inner end lies concentrically within the lower end of the tube'96 and is formed with a hollow cylindrical head 101 in which a ball valve 102 acts to normallyA close the free end of said pipe -100, suitable discharge openings 103 being provided 'in the upper end of the head 101 for obvious reasons. This form of pneumatic lift may connection with the accompanying drawings it will be seen that comparatively simple apparatus has been employed for carrying out the objects of the invention and that the,

provision of the pneumatic lifts moving over a filtering bottom .to a leaching tank, not only agitates the solutions within the tank but also prevents said filtering bottom from becoming clogged and thereby ineffective.

The solution hereinbefore mentioned may be employed in the tanks or other solutions well known to the art to which the invention relates may be employed for reproducing chemical actions upon the slimes or' ores therein. f'
